Abstract

A heavily infested egg-bed of Camnula pellucida (Scudder) was severely damaged by the predatory action of Citellus tridecemlineatus tridecemlineatus (Mitchill). This infestation, consisting of an estimated 800 eggs per square foot, was reduced by more than 90%. About half the damage occurred during the autumn after oviposition and half during the following spring prior to hatching.
